About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Create a signed 16-bit integer vector (i.e., a one-dimensional ndarray).
import Int16Vector from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-vector-int16@esm/index.mjs';Returns a one-dimensional signed 16-bit integer ndarray.
import numel from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-numel@esm/index.mjs';
var arr = new Int16Vector();
// returns <ndarray>
var len = numel( arr );
// returns 0The function accepts the following options:
- order: specifies whether an ndarray is
'row-major'(C-style) or'column-major'(Fortran-style). Default:'row-major'. - mode: specifies how to handle indices which exceed array dimensions (see
ndarray). Default:'throw'. - readonly: boolean indicating whether an array should be read-only. Default:
false.
Returns a one-dimensional signed 16-bit integer ndarray having a specified length.
import numel from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-numel@esm/index.mjs';
var arr = new Int16Vector( 5 );
// returns <ndarray>
var len1 = numel( arr );
// returns 5Creates a one-dimensional signed 16-bit integer ndarray from an array-like object or iterable.
import numel from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-numel@esm/index.mjs';
var arr = new Int16Vector( [ 1, 2, 3 ] );
// returns <ndarray>
var len1 = numel( arr );
// returns 3Returns a one-dimensional signed 16-bit integer ndarray view of an ArrayBuffer.
import ArrayBuffer from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-buffer@esm/index.mjs';
import numel from 'https://cdn.jsdelivr.net/gh/stdlib-js/ndarray-numel@esm/index.mjs';
var buf = new ArrayBuffer( 32 );
var arr1 = new Int16Vector( buf );
// returns <ndarray>
var len1 = numel( arr1 );
// returns 16
var arr2 = new Int16Vector( buf, 16 );
// returns <ndarray>
var len2 = numel( arr2 );
// returns 8
var arr3 = new Int16Vector( buf, 16, 1 );
// returns <ndarray>
var len3 = numel( arr3 );
